pi-sdk-azure: Azure endpoint is treated as an invalid URL in SDK target

[christso]

Summary

The pi-sdk-azure target fails against a real Azure-backed eval on main before scoring begins. The SDK path treats the configured Azure endpoint as an invalid URL.

Reproduction

From the AgentV repo root, with AZURE_OPENAI_ENDPOINT, AZURE_OPENAI_API_KEY, and AZURE_DEPLOYMENT_NAME set in .env and GRADER_TARGET=azure:

GRADER_TARGET=azure bun apps/cli/src/cli.ts eval run \
  examples/features/deterministic-evaluators/evals/dataset.eval.yaml \
  --test-id equals-exact \
  --target pi-sdk-azure

Expected

The eval should complete and score the exact-match test against the Azure-backed pi SDK target.

Actual

The run fails with an execution error before scoring:

pi-coding-agent SDK error (provider: openai, model: gpt-5.4-mini): "leos-m6pmw8kz-eastus2/responses" cannot be parsed as a URL.

Notes

• pi-azure does work in the same environment with a real Azure-backed eval.
• This appears to be specific to the pi-coding-agent SDK Azure path, not the CLI path.
• The error was reproduced on main on 2026-04-04.

Environment

• Repo: EntityProcess/agentv
• Branch: main
• Target: pi-sdk-azure
• Eval: examples/features/deterministic-evaluators/evals/dataset.eval.yaml
• Test id: equals-exact
